/** @brief used to delete attached via lumps from msg;
msg can be either an original pkg msg, whose Via lump I want
to delete before generating next branch, or a shmem-stored
message processed during on_reply -- then I want to
delete the Via lump for the same reason
the other case when I want to delete them is when a message
is stored in shmem for branch picking, forwarded lated and
Via removal is applied to the shmem-ed message
the same thing for Content-Length lumps (FIXME: this
should be done in a nicer way)
